Abstract
The utility model relates to a multiple heat pump with a pre-evaporation and de-frosting device, which is characterized in that a liquid transport tube on one end of a liquid storage device is connected with electronic expansion valves on the back ends of a plurality of indoor heat exchangers in series, a liquid transport tube on the other end of the liquid storage device is connected to an outdoor heat exchanger after communicating with an electronic expansion valve, and a gas transport tube on the top end of the liquid storage device is connected with the electronic expansion valve in parallel to be connected to the outdoor heat exchanger after communicating with an electromagnetic valve; the liquid storage device, the electronic expansion valves on both ends of the liquid storage device, and the electromagnetic valve on the upper end of the liquid storage device form a pre-evaporation and de-frosting device together. The opening degrees of the electronic expansion valves on the back ends of a plurality of indoor heat exchangers are big regulated, the gas transport tube on the top end of the liquid storage device is communicated with the electromagnetic valve, and thus, liquid in the liquid storage device is previously evaporated into gas with medium temperature and medium pressure, and enters the outer heat exchanger for the defrosting.
Description
Affiliated technical field
The utility model relates to a kind of multiple heat pump with prevapourising defroster, especially relates to a kind of comfort level that has simple circuit, lasting heat supply, guarantees the indoor air temperature in winter, the prevapourising defroster of reliable and energy-saving.
Background technology
It is more efficient, energy-conservation than adopting the electrical heating heat supply to adopt heat pump heat supply winter, and simultaneously, heat pump can cooling in summer.The multiple heat pump has become effective equipment commercial and family's summer in winter adjusting indoor air temperature.
When at present, known heat pump heats in the winter time the removal effect of outdoor heat converter surface frosting is still made us not too satisfied.
1. the U.S. government that announces of the WO of the World Intellectual Property Organization 99/42768 publication patented technology " heat pump " of enjoying rights with improved defrost system, 0 degree centigrade to 2.2 degrees centigrade outdoor temperature is adopted auxiliary electrically heated method defrosting, then adopt the anti-circulation of heat pump to dash the scheme of defrosting to low temperature more, influenced the comfort level of indoor air temperature in winter.
2. the patented technology " operation control system of air-conditioner " of Japanese Daikin Industries, Ltd. of announcing of the WO of World Intellectual Property Organization 95/12098 publication has adopted a kind of " indoor heat converter---compressor---outdoor heat converter---accumulator " folk prescription also can't keep the comfort level of indoor air temperature in winter to the scheme of not having circulation recoil defrosting.
3. the patented technology " method for controlling of operation of air conditioner of heat pump type " of the Japanese Matsushita Electric Industrial Industry Co., Ltd of Japan's special permission Room JP 312281/86 publication announcement has adopted the scheme of a kind of compressor while to outdoor heat converter and indoor heat converter compression defrosting, owing to broken the closed circuit of heat pump, defrosting heat that this scheme can provide and defrosting time are all very limited, and efficient is low, system is unstable.
4. the patented technology " steam compression system Defrost method and device " of the U.S. SINVENT AS company that announces of the WO of the World Intellectual Property Organization 02/18854 publication scheme that adopted multiple lasting heat supply to defrost simultaneously is promptly the method for outdoor heat converter as indoor heat converter compression defrosting.But heat pump has become complicated loop thus, has in fact also reduced the comfort level of indoor air temperature in winter.
Summary of the invention
In order to solve the above-mentioned deficiency of existing Defrost, be that defrosting efficiency is low, system complex is unstable, can not guarantee the comfort level of indoor air temperature in winter, the utility model provides a kind of different multiple heat pump with prevapourising defroster of conceiving, its loop is simple, reliable and energy-saving, can guarantee winter indoor air temperature comfortable in highly effective defrosting.
The technical measures that its technical problem that solves the utility model adopts comprise:
To decide some of frequency or frequency-changeable compressors, outdoor heat converter, some indoor heat converters, a gas-liquid separator, an oil eliminator, a liquid reservoir, check valve, electric expansion valve, magnetic valve, parts such as cross valve are formed heat pump.Wherein, some fixed frequencies or frequency-changeable compressor link side by side by a table oil separator and a gas-liquid separator, and an end woven hose of liquid reservoir and each electric expansion valve of some indoor heat converters rear end are in series, liquid reservoir other end woven hose through with an electric expansion valve UNICOM after insert outdoor heat converter, after the appendix on liquid reservoir top and the magnetic valve UNICOM again with aforementioned electric expansion valve access in parallel outdoor heat converter.Like this, the magnetic valve of the electric expansion valve at liquid reservoir and its two ends and upper end thereof is formed the prevapourising defroster jointly.
When system needs to defrost under the heat supply operating mode, each electronic expansion valve opening of some indoor heat converters rear end is transferred big, keep the heat supply running of indoor heat converter, the appendix and the magnetic valve on liquid reservoir top are open-minded, allow the liquid in the liquid reservoir flash to medium temperature and medium pressure gas and the defrosting of inlet chamber outer heat-exchanger in advance, after defrosting finishes, the appendix on liquid reservoir top and closed electromagnetic valve, each electronic expansion valve opening of some indoor heat converters rear end restores.
The beneficial effects of the utility model are, make full use of " heat pump " function of system, effectively defrosting under the prerequisite of the comfort level that does not influence the indoor air temperature in winter, and it is simple in structure understands.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the multiple heat pump configurations figure with prevapourising defroster.
1. outdoor heat converters among the figure, 2. outside electric expansion valve, 3. magnetic valve, 4. liquid reservoir, 5. indoor electric expansion valve, 6. indoor heat converter, 7. gas-liquid separator, 8. air intake duct, 9. check valve, 10. frequency-changeable compressor, 11. oil eliminator, 12. invariable frequency compressor, 13. rails, 14. cross valves.
Claims (2)
1. multiple heat pump with prevapourising defroster, comprise and decide some of frequency or frequency-changeable compressors, outdoor heat converter, some indoor heat converters, one gas-liquid separator, one oil eliminator, one liquid reservoir, check valve, electric expansion valve, magnetic valve, parts such as cross valve, it is characterized in that: some fixed frequencies or frequency-changeable compressor are formed heat pump with miscellaneous part after linking side by side by a table oil separator and a gas-liquid separator, one end woven hose of liquid reservoir and each electric expansion valve of some indoor heat converters rear end are in series, liquid reservoir other end woven hose through with an electric expansion valve UNICOM after insert outdoor heat converter, after the appendix on liquid reservoir top and the magnetic valve UNICOM again with aforementioned electric expansion valve access in parallel outdoor heat converter, the electric expansion valve at liquid reservoir and its two ends and the magnetic valve of upper end thereof are formed the prevapourising defroster jointly.
